Patented Sept. 15, 1931 v UNiTED STATES ARTHUR Mormon snaw, or NEW ORLEANS, LOUISIANA SHORE PROTECTING DEVICE Application filed September 17 1925. 'Serial No. 56,862.

The invention relates to shore protecting devices and has for its object to provide a construction of sea wall of a permanent nature, which will permit the use of well established general types of construction, but which will avoid the necessity of using heavy, expensive members, such as piling or deep foundation supports and beams for transmitting stresses to such supporting members.

Afurther object is to-provide a sea wall comprising a plurality of piling vertically disposed, and which piling has disposed on its upper end a channeled coping, into the channels of which the upper ends of the piles extend, and in a channel ofthe inner'side of which the lower end of an inclined bank protecting slab is rockablymounted, thereby allowing settlement of the slab in relation to the coping, but maintaining the adjacent side 0 of the slab in position.

A further object is to provide the inner side of the coping with an eye, with which a downwardly extending arm carried by the adjacent end of the slab engages for anchoring the slab and coping together and maintaining the same connected upon settling of the slab.

With the above and other objects in View the invention resides in thecombination and arrangement of parts as hereinafter set forth,

; shown in the drawings, described and claimed, it being understood thatchanges in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of'thc in vention. 1 i 4 In thedrawings: I Figure 1 is a front elevation of a portion of a sea wall.

Figure 2 is a vertical transverse sectional view of the sea wall.

Figure 3 is a sectional view taken on line 3 3 ofFigure 2.

Figure 4 is a vertical transverse sectional view through a modified form of sea wall, showing a right angularly disposed engagement between the slab and coping.

Figure 5 is a sectional view through a seat I wall showing an arcuate shaped engagement between the bank slab and the sea Wall coping.

Referring to the drawings, the numeral 1 designates a plurality of sheet piling which a wardly to an elevation slightly above ordi nary high tide, for instance above the water level 2. Disposed on the upper ends of the piles 1 is acoping 3, which coping is also formed from a plasticmaterial, for instance concrete and has its under side provided with a longitudinally disposed channel 4, in which the upper ends of the piles 1 are disposed, therefore it will be seen that outward or inward displacement of the coping 3 on the piles 1 is prevented. The upper inner end or corner of the coping 3 is provided with a longitudinally disposed channel'5, angular in cross section and into which the wedge shaped portion 6 of an upwardly sloping pavement or slab 7extends. The slab 7 extends upwardly and landward to anelevation above extreme storm tides. The angle which the slab makes in relation to the horizontal is slight-1y greater than the angle of natural repose of the material 8, on which it rests. Disposed behind the sheet piling 1 is a gravel pocket 9, in the bank material 8, and it will be'seen that thedraining water from the bank material 8 will seep into the gravel pocket 9 and collect therein and will be discharged from the pocket 9 through the pipe 10 from adjacent the top of the pocket back into the Water 2, therefore it will be seen that the collection of Water behind the seawall structure is prevented, and by provid such as is known commercially as preformed expansion joint material such for instance as pitch and imbedded in the lower edge of the, slab 7 and inthe coping 3 are the flanges 12 of an inverted U-shaped metallic strip 13, which metallic strip is preferably formed from a ductile material of a non corrosive character such for instance as copper, and whlch strap is also a continuous one,

' and by being U-shaped allows a considerable change in the angle of the slab 7 with relation to the coping 3 without resulting 1n a rupture of the metallic strip 13, therefore it will be seen that passage of water between the coping 3 and the slab 7 will be prevented and at the same time settlement of the slab or the coping in relation to each other Wlll not break thejoint. Disposed between the coping 3 and the slab 7 above the metallic strip 13 is a filling of pitch 14,'wh1ch.'1s

7 brought to a fluid state'by heating and is poured into the space above the metal strip 13, fully covering the strip and protecting it from wear or abrasion. The material 14 retains its semi-plastic qualities permanently so that it may become adapted to slight changes in the form of the spacewhich it fills, resulting from a lowering of the back or landward edge ofthe slab 7. Extending downwardly from theslab-7 adjacent to its lower edge is an arm 15 which is imbedded in the slab andwhich arm' terminates in a hooked end 16, which extends through alior izontally disposed eye 17 carried by thebar 18, which is imbedded in the coping 3". The arms 15, 18'and the eye 17 are formed preferably of corrosion resistent metal for instance cast iron, and are each imbeddedin its re-- I spective portion of I the structure. These hooks and eyes are to be placed at suitable intervals along'the line of the structure, and they prevent any movement of the slab away from the copingB, but at the same time permit a slight arcuate movement of the slab about these points as a hinging connection.

It is obvious that the slab 7 may be formed from small or relatively large sections as desired, however the slab sections are provided with expansion joints 19 formed of pitch or other material'and the slab sections are con-5 nected together by means of a pliable metallic strip 20 similar to-the strip 13, and which strip 20 and expansion joint compensate for lateral movement which may occur in the slab sections as the result of temperature stresses and also to give the structure flexibility which will permit each section of the slab 7, to adjust itself automatically to possible va riations in the amount of settlement or subsidence of the supporting earth. Disposed beneath the metallic strip is a semiyieldable material 21 similar to the material 11.

Referring to Figure 4 the structure is substantially the same as that shown in Figure 2 with the exception that the coping channel 5a in the coping 3a is right angularly shaped in cross section and the interengaging arms 15 and the eye- 17 eliminated otherwise the structure is substantially the same and the same numerals apply thereto.

Referring to Figure 5 wherein a further modified form is shown the structure is the same as shown in Figure 4 with the exception that an arcuate shaped channel 5?) is provided in the coping 3b. I

From the above it will be seen that a seawall is provided and a bank slab in connection therewith which is of a permanent nature, provided with interengaging means for preventing displacement of the parts in rela-' tion'to each other means is provided where- ,bywater will be prevented from' seeping through the joints of the structure, yet said joints are of a pliable nature thereby allowing settlement of the bank slab parts without breaking the joints. It will also be seen that means is-provided for discharging seepage water from behind the sheet piling;

The invention having been set forth what is claimed as. new and useful is 1. A sea Wall comprising a vertically disposed wall, a coping disposed on the upper end of said wall, the upper. end of said wall being disposed in'a longitudinally disposed channel in the underside of the coping, an

upwardly and inwardly inclined bank slab,

the lower end of said bank slab being rockably disposed in a channel in the inner. side of the coping and a positive rocking connection between said slab and coping to the rear of the coping. I

'2. A sea wall comprising a vertically disposed wall, a coping carried by said wall, an

upwardly and inwardly inclined bank slab,

the slab, a rearwardly extending member carried by the coping, said arm and member being rockably interengaged. I r i In testimony whereof I hereunto aflix my signature.
